SHAFT-COUPLING.

SPECIFICATION forming part of Letters Patent No. 267,185, dated August9, 1904.

Application filed May 12, 1904.

To (LZZ whom it may concern:

Be it known that I, AnoLri-iin THUILLIER, a citizen of the United Statesof America, residing at Hazelwood, in the county of Allegheny and Stateof Pennsylvania, have invented certain new and useful Improvements inShaft-Couplings, of which the following is a specification, referencebeing had therein to the accompanying drawings.

This invention has relation to shaft-couplings in general, and moreparticularly to that class in which a coupling may be employed to holdtwo sections of a shaft whereby they may turn in unison or may rotateindependently and yet preserve their alinement and location.

The object of my invention is to construct a coupling of theabove-described character which may be easily and quickly secured to twoshaft-sections, and in constructing my improved coupler I have made thesame dustproof and in such a form that it serves the function of alubricator.

Briefly described, my improved shaft-coupling consists of two coneshaped sections which are placed together, a metallic ring beinginterposed between said sections, and in the adjoining faces of eachcone-shaped section I have provided an annular recess, with whichcommunicate lubricating-ports from the exterior of the cone-shapedsections, and over these sections are placed two clamping members whichsecure the cone-shaped sections together and form alubricating-receptacle for the shaft-sections.

The above construction will be hereinafter more fully described, andspecifically pointed out in the claims, and in describing the inventionin detail reference is had to the accompanying drawings, forming a partof this application, wherein like numerals of reference indicate likeparts throughout both views, in which Figure 1 is a vertical sectionalview of my improved shaft-coupling, showing the same mounted upon theends of two axle-sections;v and Fig. 2 is a central transverse sectionalview of the same.

In the accompanying drawings the reference-numerals 1 and 2 indicate twosections of an axle upon which my improved shaft- Serial No. 207,687-(No model.)

coupling is mounted, and in Fig. 1 of the drawings I have illustratedthe coupling as connecting together two car-wheels, and the reference-numerals 3 and 1 designate two cone-shaped sections which are identicalin construction, and I will therefore only specifically describe one ofsaid sections. The cone-shaped section 3 is provided with an annularrecess 5 in its one end or the base portion of the cone. Intermediatethis annular recess 5 and the periphery of the cone-section I provide anannular groove 6, which when the two cone-shaped sections are placedtogether, as illustrated in Fig. 1 of the drawings, coincides with asimilar groove carried by the cone-shaped member 4, forming an annularpocket, in which is placed a metallic ring 7, and as the cone-shapedsection 4: is formed with an annular recess similar in construction tothe annular recess 5' of the conesection 3 these two sections whenplaced together form an annular pocket 8, the object of which will behereinafter more fully described. The periphery of the cone-shapedsection 3 is beveled upon its two edges, as indicated at 9 and 10, andupon the shank portion 11 of the cone-shaped section I provide anannular collar 12, this collar being formed upon the shank at a pointwhere the contour of the cone leaves the shank portion of thecone-shaped section. The cone-shaped section is provided with ports 14:,which are drilled at an angle to the longitudinal axis of thecone-shaped sections, and these ports communicate with the annularpocket 8 of said sections.

In order to secure the two cone-shaped sections together,I employ twosemicircular members 15 and16,these members carrying flanges 17 17 and18 18, the flanges of each member being secured together by thescrew-bolts 19 and the nuts 20 20. These semicircular members areidentical in construction, and each one of said members forms a hoodover the cone-shaped portions of the sections 3 and 4:. The semicircularmembers are formed with angular sides 21, and the lower edges of thesesides have a depending flange 22, said flanges being provided with aplurality of apertures 23, and when the two members 15 and 16 are placedtogether upon the cone-shaped sections 3 and 1 the depending flanges ofeach semicircular member 15 and 16 form a flat annular surface, againstwhich is secured a felt ring 24:, said rings being secured on thedepending flanges by screw-bolts 25, which engage in the apertures 23 ofsaid flanges, and the felt rings 24 are adapted to engage the shankportions 11 of the cone-shaped sections 3 and i, this constructionproviding a dust proof shaft-coupling, which will hereinafter be morefully described.

Each of the semicircular members 15 and 16 is provided with an annulargroove 26, which when the members are placed over the cone-shapedsections 3 and 1 forms a seat for the base portions of the cone-shapedsections comprising the coupling, and by the construction of the angularsides of the members 15 and 16 two annular compartments 2? 27 areformed.

It will be observed from the construction of my improved shaft-couplingthat I have provided a lubricator for the axle or shaft sections whichare to be coupled together, and. to lubricate the shaft or axle thescrewbolts 25 are removed and the lubricating oil or material isinjected into the annular compartments 27 through the apertures 23 ofthe depending flange, or the felt ring 2a may be removed and the oil ormaterial placed in the compartment 27. The lubricating material placedin these compartments flows through the ports let and into the annularpocket 8, formed by the two cone-shaped sections 3 and 4, and thelubricating oil or material will then find its way between the abuttingfaces of the sections 3 and 4c and surround the metallic rings 7, fromwhence it will gradually pass to the annular pocket 29, formed by thebeveled edges 9 9 of the sections and 1, thoroughly lubricating allabutting faces of the coupling, at the same time lubricating theabutting ends of the axle or shaft sections. I have provided the annularcollars 12, whereby the lubricating oil or material will be preventedfrom coming into contact with the felt rings 2a and the seepage of theoil through the felt rings prevented, and by placing the inner edges ofthese felt rings in engagement with the shank portions 11 of thesections 3 and L all dust, dirt, or ingredients foreign to the generaloperation of the shaft or axle sections is prevented from entering thecompartments 27, which are in communication with the abutting ends ofthe shaft or axle sec l with two shaft-sections, of two cone-shapedsections, provided with an annular pocket formed in adjacentfaces, portscommunicating with said pocket, an annular ring interposed between saidsections, and means for securing said sections together.

2. In a shaft-coupling, the combination with two shaft-sections, of twocone-shaped sections having annular collars formed thereon, saidsections having annular pockets formed therein, and ports communicatingwith said pockets, annular grooves formed in said sections, a metallicring mounted in said grooves and means for securing said sectionstogether.

3. In a shaft-coupling, the combination with two shaft-sections, of twocone-shaped sections having annular collars formed thereon, each of saidsections having an annular pocket formed therein, each of said sectionshaving an. annular groove formed therein, a ring in said grooves, twosemicircularhollow members ada 'ited to fit over said sections and meansfor securing said members together, substantially as described.

1. In a shaft-coupling, the combination with two shaft-sections, of twocone-shaped sections, an annular pocket formed in said sec tions, portscommunicating with said pocket, an annular ring interposed between saidsec tions, two hollow members adapted to fit over said sections, feltrings carried by said mem bers, and means for securing said memberstogether, substantially as described.

5. In a shaft-coupling, the combination with two shaft-sections, of twocone-shaped sections, having annular collars formed thereon, a pocketformed in said sections, said coneshaped sections having ports formedtherein communicating with said. pocket, an annular ring interposedbetween said sections, two semicircular hollow members adapted to fitover said sections, felt rings carried by said members and adapted toengage the coneshaped sections, and means for securing said memberstogether, substantially as described.

6. A shaft-coupling comprising two coneshaped sections having annularcollars formed thereon, said sections having" annular recesses formedtherein, said sections having annular grooves formed therein, a ringmounted in said grooves, two semicircular hollow members adapted to litover said sections and secure the same together, felt rings carried bysaid members and adapted to engage the coneshaped sections, and meansfor securing said members together, substantially as des .-.ribed.
